Hello dear jhonatamvitalino, Let me explain how it works and why you need it.

Let’s imagine you have some articles on site or blog – all articles are divided into categories and tags. Let’s say you have 1000 articles on your site. 300 articles have a category of e.g. Places. You need to add to this 300 articles links to your social networks because they are the most viewed articles on your site, and these links will provide you a lot of new subscribers.

So, what you shall do:

You create a new Extra Content Item;

Add text with links to social networks;

Choose the category Places where you want to add links to social networks;

Publish it.

Then you can see in all of the 300 articles with the category Places the links to your social networks.
